This name is hardly if ever used for girls. It is the name of the female author of the incredible book "To Kill a Mockingbird." (Harper Lee) It also has a sort of southern flair. A good name for a male sibling to compliment it could be Wyatt or Peyton.

Harper comes from an English surname meaning "harper; one who plays the harp." It was brought to public attention by the author Harper Lee (born Nelle Harper Lee in 1926) whose most famous work to date was the 1960 novel To Kill a Mockingbird.
